AUTOMATIC GATE.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed August 14, 1917. Serial No. 186,137.

To all whom it may concern:

Be it known that I, EDWARD SNICKERS, a citizen of the United States, residing at Matlock, in the county of Mason and State of Washington, have invented certain new and useful Improvements in Automatic Gates; and I do hereby declare the following to be a'full, clear, and exact description of the ini vention,such as will enable otherskilled in the art to which itA appertains to make and use the same.

Thisinvention relates to improvements 1n an automatic gate especially adapted for use in connection with scales for the purpose of preventing an unauthorized person from using the scale whenever desired.

Another object of this invention is the provision of a gate normally disposed over the scale and which is capable of being ren-` dered inoperative when in this position to prevent the use of the scale. u.

A further object of this invention is .the

g; provision of a means for automatically opening the Gate' upon the arrival of a vehicle 'orthe lilie on the scale.

A still further object of this invention is the provision of an automatic gate of the i above stated character, which shall be simple, durable and eiiicient, and which may be manufactured and sold at a comparatively low cost. Y

With these and other objects in view as will become more apparent as the description proceeds', the invention consists in certain novel lfeatures of construction, combination and arrangement of parts as will be hereinafter `more fully described and claimed.

Fig. 5 is a detail sectional view taken on the line 5 5 of Fig. 4,

Fig. 6 is a perspective view of the means for locking the gate in a closed position,

Fig. 7 is a fragmentary sectional view of the means for swinging the gate in an open poslition and adapted to be actuated by the sca e, c

Fig. 8 is a detail sectional view illustratinothe locking means applied to the scale,

eferring in detail to the drawings, the

numeral l indicates as an entirety, a scale consisting of a platform, which has secured thereto, a plurality of downwardly depending supporting rods or bolts 3, which have mounted thereon, coiled springs 4l. The platform 2 is positioned within a casing 5, which is embedded in the ground as shown in Figs. 1 and 2. The casing 5 has secured thereto, a plurality of transverse strips 6, that are provided with apertures to slidably receivel the lower ends of the supporting rods 3 and on which the lower ends of the coiled springs 4 bear to supportthe platform 2 in an elevated position. The platform 2 has secured to each corner thereof, guide plates 7 that engage within the side Walls of the casing 5 to prevent the platform 2 from becoming displaced within the casing 5. The casing 5 is provided with an opening in one side thereof in which is positioned, a substantially U-shaped housing 8 in crossI section.y

Thel substantially U-shape housing 8 is secured to the platform 2 and to the under face thereof in any suitable manner and is adapted to receive a gate actuating means, which will be hereinafter more fully de scribed.

A supporting post 9 is positioned in the ground along one side of the scale 1 and at a point intermediate its ends and has secured thereto, a pair of plates 10, which support a gate supporting post or member 11. The member 11 is provided with reduced portions 12 adjacent its ends on which are formed, spirals 13. A gate 14 of substantially rectangular formation has formed on one end thereof, extensions 15 that are recessed to receive arms 16 that are provided with a plurality of apertures. Cylindrical members 17 surround the reduced portions 12 of the supporting post or member 11 and have formed thereon, extensions 18 that rcceive the extensions 15 of the gate 14: and overlie the arms 16. Extensions 18 are provided with apertures which aline with apertures in the arms 16 and with apertures in the extensions 15 to receive bolts whereby the arms and extensions 18 are secured to the extensions 15 of the gate 141. When the gate is in its normal position or over,g lying the scale, as shownin Fig. 2, thearms 16 are received within notches 19 formed in the gate supporting post or member 11; Rollers 20 are journaled to the arms 16 and ride upon the spirals 13 when the gate is swung to an open position so that the gate will return to its normal position or closed position under its ownweight. Projections 21 are formed upon the lower end ofthe supporting post or member 11, which support the lower cylindrical memberv17 upon the gate when the gate is in a closed posi#- tion. These stops or projections 21 limit the movement of the gate to al closed position. An arm 22 is provided with a reduced extension 23 which extends through anV aperture in the lower edge ofthegate 14 and receives a nut 24, whereby the arm 22 is rotatably connected-to the gate, The arm 22 has its other end enlarged to form a journal 25 to receive a reduced extension 26 formed upon a substantially L-shaped member 27 .v

The substantially L-shaped member 27 has formed thereon, a collar 28, which supports the bearing 25 upon the arm 22. A nut 29 is threaded `to the reducedcxtension 26 after being passed through the journal-25- A lever 30 is pivoted to the other end of the substantially L-shaped arm 27 by `a pin and slot connection and has itsfree end disposedwithin the substantially U-shaped member 8;of the scalel, asclearly shown vin Fig. 7.

. A plate 31 is secured to the casi-ng' 5 ofl the scale 1 adjacenty the opening in the casing and has formed thereon, eyelets 32 to rotatably receive a rod 33. The road-33 has formed thereon, a handle34, which is disposed exteriorly of the casing 5 for the purpose of rotating the rod 33 within the eyelets 32. The rod 33 is provided withan offset portion 35, which isdisposed transn versely of the opening in the scale or casing 5 and has yjournaled thereon, the lever 30. The lever 30'has secured toits inner end, an upwardly directed member 36, which has its free end'disposed against the substantially U-shaped member 8, which is secured to the under face of the platform 2 of the scale 1.

A coiled spring 37 is secured to the substantially L-shaped member 27 adjacent the collar 28 and to the lever 30 as shownv at 38.

In operation, when itis desired to render thel gate inoperative or fromhbeing swung to an open position, the ofsetportion 35 ofthe rodf33 is swungI downwardly so as to move the mem-ber 36 upon the lever-30 from engagement with the member 8 on the platform 2, so that whena vehicle moves ontov the platform on one end thereof, the-platformv will notl rock the lever 30 uponits pivot, owing to that fact that the member 36 is disposed at such apoint that the platform 2 willv not engage the same when moved downwardly under the influence of the weight of the vehicle, thus preventing the vehicle from moving entirely onto the platform 2 of the scale 1. When it is de-4 sired to permit the gate to automatically open upon a vehicle moving onto the platform 2, the olfset portion 35. of thetrod33. is. disposed upwardly so astopositionthe member 36 into engagementwiththe.- sub;- stantially U-:shaped member 8' .carried by the.

platform 2, and as. the: platform 2.1. moves; downwardly under theV influence,l of'z the.,

upwardlyandupon furtherr movement,the gate swings to an open position, owing t0..-

the rollers 20traveling` upon the-spirals, 13. The gate-will maintain this openpositlon until the vehicle: movesy oif ofthe: platform 2',- permitting thev` platform to, return to, its.; normal position. Aspthe platform 2 :II10YBSL:

to its` normal position, therollers;v resting upon the upper endsofthe spirals ywilll move;

downwardly. thereon,l causing the gate to;

move to a closed position. v

While I have showny and described; the; preferred embodiment of my invention,it will beunderstood that minor changes x. in construction, combination; and;y arrangement; of parts may be-madewithout departing;v from the spirit! and scope offthe invention as claimed;
